Connecting medical professionals is about to get easier thanks to a new Houston company, Flourishing Nexus.

Next month, their digital platform, The Nexus, will debut to in a soft launch to a curated group of TMC employees.

“Think of it as a combination of existing platforms like LinkedIn, providing professional networking; Khan Academy, which provides excellent training and education; and a collaborative workspace like Google Workspace or Microsoft Teams, all enhanced by AI,” says Diane Nguyen.

Nguyen is a pharmacist by training, while her co-founder, Satid Thammasitboon, is an MD and master in health professions education.

The pair began working together in the health professions education space three years ago, but only established Flourishing Nexus in July of 2023. The company’s moniker refers to the concept of human flourishing.

“Our mission would be to promote human flourishing among health professionals,” says Thammasitboon.

The concept of human flourishing traces back at least to Aristotle, but The Nexus’ understanding of it is based on psychologist and educator Martin Seligman’s PERMA theory. The mnemonic stands for Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment.

“We endeavor to bring these concepts of PERMA and human flourishing into the health professions space,” says Nguyen.

“Often our healthcare organizations or industries, when they hear health professionals are having issues with burnout, the response or reaction would be to increase incentive, financial support, or professional development to enhance resilience,” adds Thammasitboon. “We search for meaning we want to make a difference in the life of another rather than ‘everything is all about money.’”

Both professionals have globe-spanning careers. Thailand native Thammasitboon says that his endeavors have taken him across Europe, Southeast Asia, and East Asia, while Nguyen’s work has focused her attention on South America, sub-Saharan Africa, and Eastern Europe.

“I realized that the key to providing better outcomes and health care for the patients was really dependent on the continuing education and training of the staff,” Nguyen says.

Those experiences proved to be the roots from which The Nexus grew.

But the team’s colleagues abroad won’t be among the first The Nexus users. That distinction will belong to Houston’s rich community of medical pros. And when the platform soft launches in January, it will be with two awards already under its belt.

The Liftoff Houston Startup Business Plan competition took place last month. Nine finalists, mostly entrepreneurs from underrepresented backgrounds, were selected from among 100 applicants to compete in Liftoff’s Pitch Day. Not only was The Nexus among those competitors, it raked in a runner-up prize, as well as fan favorite in the innovation category.

Nguyen, who did the pitching, says that Liftoff helped Flourishing Nexus tremendously with both its preparation workshops and feedback from the judges.

“Sometimes you think you have a great idea but it’s not until you critically think about your own plan, analyze your plan, and prepare to pitch it that you really learn about it. This preparation helped us and strengthened our mission. Our business plan is much better,” says Thammasitboon.

Next up? Launching and growing The Nexus’ community. Nguyen also says they plan to participate in more competitions, including possibly Houston Community College’s Business Plan Competition. It’s one more way of bringing the abstract concept of human flourishing to a flesh and blood audience.

Greentown Labs has named Lawson Gow as its Head of Houston.

Gow is the founder of The Cannon, a coworking space with seven locations in the Houston area, with additional partner spaces. He also recently served as managing partner at Houston-based investment and advisory firm Helium Capital. Gow is the son of David Gow, founder of Energy Capital's parent company, Gow Media.

According to Greentown, Gow will "enhance the founder experience, cultivate strategic partnerships, and accelerate climatetech solutions" in his new role.

“I couldn’t be more excited to join Greentown at this critical moment for the energy transition,” Gow said in a news release. “Greentown has a fantastic track record of supporting entrepreneurs in Houston, Boston, and beyond, and I am eager to keep advancing our mission in the energy transition capital of the world.”

Gow has also held analyst, strategy and advising roles since graduating from Rice University.

“We are thrilled to welcome Lawson to our leadership team,” Georgina Campbell Flatter, CEO of Greentown Labs, added in the release. “Lawson has spent his career building community and championing entrepreneurs, and we look forward to him deepening Greentown’s support of climate and energy startups as our Head of Houston.”

Gow is the latest addition to a series of new hires at Greentown Labs following a leadership shakeup.

Flatter was named as the organization's new CEO in February, replacing Kevin Dutt, Greentown’s interim CEO, who replaced Kevin Knobloch after he announced that he would step down in July 2024 after less than a year in the role.

Houston foundation grants $27M to support Texas chemistry research

fresh funding

Houston-based The Welch Foundation has doled out $27 million in its latest round of grants for chemical research, equipment and postdoctoral fellowships.

According to a June announcement, $25.5 million was allocated for the foundation's longstanding research grants, which provide $100,000 per year in funding for three years to full-time, regular tenure or tenure-track faculty members in Texas. The foundation made 85 grants to faculty at 16 Texas institutions for 2025, including:

  • Michael I. Jacobs, assistant professor in the chemistry and biochemistry department at Texas State University, who is investigating the structure and thermodynamics of intrinsically disordered proteins, which could "reveal clues about how life began," according to the foundation.
  • Kendra K. Frederick, assistant professor in the biophysics department at The University of Texas Southwestern Medical Center, who is studying a protein linked to Parkinson’s disease.
  • Jennifer S. Brodbelt, professor in chemistry at The University of Texas at Austin, who is testing a theory called full replica symmetry breaking (fullRSB) on glass-like materials, which has implications for complex systems in physics, chemistry and biology.

Additional funding will be allocated to the Welch Postdoctoral Fellows of the Life Sciences Research Foundation. The program provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas. Two fellows from Rice University and Baylor University will receive $100,000 annually for three years.

The Welch Foundation also issued $975,000 through its equipment grant program to 13 institutions to help them develop "richer laboratory experience(s)." The universities matched funds of $352,346.

Since 1954, the Welch Foundation has contributed over $1.1 billion for Texas-nurtured advancements in chemistry through research grants, endowed chairs and other chemistry-related ventures. Last year, the foundation granted more than $40.5 million in academic research grants, equipment grants and fellowships.

“Through funding basic chemical research, we are actively investing in the future of humankind,” Adam Kuspa, president of The Welch Foundation, said the news release. “We are proud to support so many talented researchers across Texas and continue to be inspired by the important work they complete every day.”

New Houston biotech co. developing capsules for hard-to-treat tumors

biotech breakthroughs

Houston company Sentinel BioTherapeutics has made promising headway in cancer immunotherapy for patients who don’t respond positively to more traditional treatments. New biotech venture creation studio RBL LLC (pronounced “rebel”) recently debuted the company at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.

Rima Chakrabarti is a neurologist by training. Though she says she’s “passionate about treating the brain,” her greatest fervor currently lies in leading Sentinel as its CEO. Sentinel is RBL’s first clinical venture, and Chakrabarti also serves as cofounder and managing partner of the venture studio.

The team sees an opportunity to use cytokine interleukin-2 (IL-2) capsules to fight many solid tumors for which immunotherapy hasn't been effective in the past. “We plan to develop a pipeline of drugs that way,” Chakrabarti says.

This may all sound brand-new, but Sentinel’s research goes back years to the work of Omid Veiseh, director of the Rice Biotechnology Launch Pad (RBLP). Through another, now-defunct company called Avenge Bio, Veiseh and Paul Wotton — also with RBLP and now RBL’s CEO and chairman of Sentinel — invested close to $45 million in capital toward their promising discovery.

From preclinical data on studies in mice, Avenge was able to manufacture its platform focused on ovarian cancer treatments and test it on 14 human patients. “That's essentially opened the door to understanding the clinical efficacy of this drug as well as it's brought this to the attention of the FDA, such that now we're able to continue that conversation,” says Chakrabarti. She emphasizes the point that Avenge’s demise was not due to the science, but to the company's unsuccessful outsourcing to a Massachusetts management team.

“They hadn't analyzed a lot of the data that we got access to upon the acquisition,” explains Chakrabarti. “When we analyzed the data, we saw this dose-dependent immune activation, very specific upregulation of checkpoints on T cells. We came to understand how effective this agent could be as an immune priming agent in a way that Avenge Bio hadn't been developing this drug.”

Chakrabarti says that Sentinel’s phase II trials are coming soon. They’ll continue their previous work with ovarian cancer, but Chakrabarti says that she also believes that the IL-2 capsules will be effective in the treatment of endometrial cancer. There’s also potential for people with other cancers located in the peritoneal cavity, such as colorectal cancer, gastrointestinal cancer and even primary peritoneal carcinomatosis.

“We're delivering these capsules into the peritoneal cavity and seeing both the safety as well as the immune activation,” Chakrabarti says. “We're seeing that up-regulation of the checkpoint that I mentioned. We're seeing a strong safety signal. This drug was very well-tolerated by patients where IL-2 has always had a challenge in being a well-tolerated drug.”

When phase II will take place is up to the success of Sentinel’s fundraising push. What we do know is that it will be led by Amir Jazaeri at MD Anderson Cancer Center. Part of the goal this summer is also to create an automated cell manufacturing process and prove that Sentinel can store its product long-term.

“This isn’t just another cell therapy,” Chakrabarti says.

"Sentinel's cytokine factory platform is the breakthrough technology that we believe has the potential to define the next era of cancer treatment," adds Wotton.
